Quartzite tile flooring

I used Quartzite floor tiling in my house during renovation. It looked very good and i was very impressed with this.But i like to have some variation. Can anyone suggest me any other forms these stones are available in the market? All suggestions are welcome.

Quartzite has tons of variation, from gold, red, green colors to dark grey. Probably one with the huge color variation is Golden White Quartzite as you can see that on our website http://www.cdtilestone.com/p/131/golden-white-quartzite-tile or on Google https://www.google.com/search?q=quartzite+tile&source=lnms&tbm=isch&sa=X&ei=7jUyUv_qIMqpigKS34CgBg&sqi=2&ved=0CAcQ_AUoAQ&biw=1920&bih=976&dpr=1
